Raymarine B265 LM Chirp 1kW Thru-Hull Transducer

PRODUCT ID: RM1184-110 MFG ID: A80011

Raymarine B265 LM 1kW FM and Chirp Broadband Thru-Hull transducers represent the next generation of technology that will allow fishermen to unlock new secrets in fishfinding. Raymarine B265 transducers are designed for use specifically with Broadband, CHIRP, FM, and Spread-Spectrum fishfinders.

CHIRP Fishfinders transmit across a wide frequency band instead of using a single frequency. This is also known as “Frequency Modulation” or “Spread-Spectrum” Transmissions. These waveforms are typically of long duration and for example may start at 42 kHz and end at 65 kHz. Energy transmitted into the water can be 10 to 50 times greater than a traditional fishfinder. By storing the shape of the transmitted waveform in memory and comparing it to the received echoes using pattern matching techniques (also called pulse compression), it is possible to find targets within the noise and precisely determine their range with astounding accuracy.

Extreme target detail and image resolution at all depths

Precise separation between baitfish and gamefish

Bottom discrimination of fish laying on the seabed

Deep sounding accuracy down to 3,000 m (10,000’)

Ability to detect targets at greater depths & higher speeds

Ability to find targets within the noise (“snow” on the display)

Frequencies*:

Low-Frequency Options (LF): 28 kHz to 75 kHz

Medium-Frequency Options (MF): 85 kHz to 135 kHz

Beamwidths*:

LF: 12° to 25°

* Frequency band and beamwidth vary with model—see specific model for details.

Our Price is Too Low to Advertise

Many of our manufacturers have a Minimum Advertised Price (M.A.P.) policy. This restricts us from advertising prices below a certain price which in many cases is higher than our everyday low price. In order to maintain our commitment to deliver our customers the lowest prices available, we must present our prices for products within M.A.P. pricing guidelines.
